ence being had to the accompanying drawings.

My invention relates to roundabouts or. moving amusement apparatus having ears,

or other novel means for riding.

Thelobject of my invention is to provide an amusement apparatus of the type described in Letters Patent No. 958,119 heretofore issued to me on March 29, 1910,`for an improvement in roundabouts, andparticularly for improvements upon and certain novel arrangements adapted to thev device described in -said patent. I now propose to provide the laforesaid device with cones or frustums upon the platform or table, the former having peculiarly arranged -tracks thereon along which the cars shall travel. I attain these objects, as well as other distinct advantages, by the mechanism, con'- struction and arrangement of parts illustrated in the accompanying drawings, which form a part hereof.

Figure 1 is a sectional side elevation of the roundabout showing my device arranged thereon in the form of a cone andffrustum. Fig. 2 is a sectional side elevation of the roundabout showing my device arranged thereon in the form of frustums. Y

Like letters and numerals refer to lke parts. y f

A is a socket secured to the earth.

B is a shaft, having anV integral rounded lower end 3,*adapted to rotate in the socket Ain an inclined position.v

l C is a circular table or platform, the center of which is secured upon the upper end of the shaft B. The table is rigidly secured upon the shaft by means of the system of stay braces D. A circular track D is secured upon the earth at a distance fromA the lower end of the shaft Bwhich will allow the rim of the tableto roll thereon. A circular track 1 is arranged upon the outermost surface of the tablev C. An outside continuous guard railing 5 is provided on the edge of the table: A car G provided with power means to drive it is placed upon the track A. The car 6 is also provided with guide rollers 7 which engage the guard rail.-

ing 5'. A cone shell 8 is arranged onV the table C. The cone shell 8 has an opening'Q in its apex and an interior partition 10a little below the apex.V A helical track 11,

having a railing 12, is arranged about the exterior of the cone shell 8, and'tubs 13 lare placed upon said track. The pitch of the helical' track 11 is arranged and fixed with relation to the inclination of the surface of Vthe table C. The cone shell 8 has an inlet '14 mits upper part, through whichinlet the track 11 leads at its highest point of elevation. There is also an outlet 14 in the cone shell 8 at its base.

Within the cone shell 8 is a second cone shell or more preferably a frustum shell 16,

Vras shown in Fig. vl. A helical track 18 with rail 19 is arranged about the exterior of the frustum 16 in the vsame direction as that of the track 11. The track 18 joins with ythe track 11 at the inlet 14 and from there extends to the outlet 14 and there joins the track 11 at its lowest point. The pitch of this track is arranged'and fixed in the same manner as that of the track 1l.

Ink Fig. 2 I show anarrangement ofthe `upon the interior of anl inverted inner frustum 28. The outer frustum 2O in Fig'. 2 and the table and motor car are similar to what yis seen in Fig.l y1 except that the track 11 leads directly into'tlie exposedV track 21 of same track upon a frustum 20, as is illusy the inner Yfrustum 23 which track 21 extends in the same direction to the outlet 14 and thence into the track 11. Cars 18 are yplaced on the track 11 inFig. 2. The principle involvedin the arrangement of ythe tracks upon the frustums' of Fig. V 2 is identical'with that shown in'Fig. 1. f

It will now be seen that when 'my device is assembled 'in operative position as shown in Fig. 1, with cars or tubs placed uponfthc tracks, the motor 6 is started. This causes tlie'table C to roll upon the track D. The rolling movement of the table causes the helical track 11 to move in a manner to impart an upward helical path of travel to a car orV tub on the track. all Vthe cars or tubs in that track to travel in their respective order from the surface of the table to the highest point of the track 11,'then to enter thetrack 18 through .the inlet 14. From that point the tubs or This causes cars travel downward in like manner, and

. they emerge through in the same direction, on the track 18 until an outlet lll ofthe cone 8 upon the track ll and Vagain pursue the same course of travel.

, In Fig. 2 it will be observed that a car or. tubrstarting at the lowest' point-inthe track 11 travels upward in the same 1nani ner, and, at the highest po-int, enters upon 'y helical ofthe coneA shell less than that shown in the drawings to 35 fIt will likewise beseen, motor car travel, that the 15V Vvmy invention.
